介绍系统工作原理、硬件设计、软件设计及提高系统可靠性措施,并对系统功能、特点和它在试验现场所起的作用给予说明。经多年实践证明,由于它能实时给主试验员提供试验状态主要数据、显示试验状态与计算特性状态的逼近程度,为主试验员排气、节气以及调整工况带来极大方便,从而提高了试验效率和经济效益。 The working principle of the system, hardware design, software design and measures to improve the system reliability are introduced. The functions and characteristics of the system and the role it plays in the test site are given. After many years of practice it has been proved that since it can provide the main examiner with the main data of the experimental state in real time, it shows that the state of the experimental state and the approximation of the calculated characteristic state are very convenient for the main experimenter to exhaust, regulate the gas and adjust the working conditions so as to improve The test efficiency and economic benefits.
